Synteny blocks in C. elegans vs. 100kb fragmented C. elegans. Chromosomes are separated into panels labelled with Roman numerals. The Y axis stands for categories of distribution. Synteny blocks defined by five detection programs: DAGchainer (red), i-ADHoRe (yellow), MCScanX (green), SynChro (light blue), and Satsuma (blue) are drawn as rectangles. Gene distribution is represented by the bottom smaller rectangles in burgundy. The X axis is the chromosome position. (PNG 322Â kb
